Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterAir Duct Cleaning Company in Covina, CA
Air duct cleaning in Covina runs $450 – $850 for a standard single-system home, with a full HVAC deep-clean including coils, blower, and sanitizer falling between $650 and $1,100. We’re Linden Air Duct Cleaning, and we work on Covina homes every week. Covina sits at the base of the San Gabriel Mountains in one of the most smog-trapped air basins in the country, which means the dust you see on your registers is not the same dust homeowners deal with in West Covina or Baldwin Park. It is finer, it carries more ash, and it accumulates faster. If you want an exact price before anyone steps through your door, call (980) 447-2498.
Why Covina Homes Are Different
Covina was largely built out during the 1950s – 1970s suburban boom, and that matters for ductwork. A lot of the homes we see on the north end of town, up near Badillo Street and the foothills, still run their original sheet-metal runs or early flex duct. The mastic seals at the joints have dried and cracked. The return-air side of the system pulls unconditioned air from attics that bake all summer. None of that is unusual for the San Gabriel Valley, but Covina adds something flatland cities don’t deal with: geography.
Prevailing westerly winds push particulate matter from the LA basin eastward until it stalls against the mountains directly above Covina. The result is a persistent temperature inversion that holds fine PM2.5 over the valley floor, especially on hot afternoons when every home on the block is running central air. Your HVAC system pulls that polluted outdoor air through the return vents and deposits it inside the ductwork. Add Santa Ana wind events that sweep desert dust and ash down from the Angeles National Forest in the fall, and you get ducts that load up with particulate far faster than the same system would in, say, Baldwin Park. It is not a maintenance luxury here. It is a function of where the city sits.
We also flag something most Covina homeowners never hear: some pre-1980 construction includes duct insulation containing asbestos. Before any cleaning work begins on an older home, our technicians identify the insulation type and stop if there is any question. That is not alarmism. It is a real safety step that matters more in Covina’s older housing stock than in newer SGV developments.
Our Main Covina Services
These are the two services Covina homeowners call us about most often, along with the repair option for when cleaning reveals something that needs actual fixing.
Air Duct Cleaning in Covina
Covina’s foothills-adjacent homes collect dust differently than the flatlands. After fire season in the Angeles National Forest, we routinely pull thick deposits of fine ash and char from duct systems north of the 210. The cleaning itself is negative-pressure extraction: we seal the system, create a vacuum at the main trunk, and agitate each supply and return run so the dislodged particulate gets pulled out rather than pushed into your living space. We also clean the blower, coils, and drain pan, since a heavy buildup there shortens your HVAC’s life. Every job includes a written price before we start and before-and-after photos of your own ducts. See the full Covina service breakdown here: Air Duct Cleaning in Covina.
Dryer Vent Cleaning in Covina
Dryer vents in Covina clog with two things: lint and the same fine dust that settles everywhere else in the house. Older tract homes especially run vent runs that are long, often with multiple elbows, and sometimes terminate on the roof. That setup traps lint faster than a short side-wall run. What we find most is the lint trap bypass: the lint screen catches the big stuff, but the fine particles get through and pack themselves into the vent over time. The restriction makes your dryer run longer and the exhaust temperature climb. Lint is fuel, and a clogged vent is a fire hazard. We clean the full run from the dryer to the exterior termination. The Covina-specific page is here: Dryer Vent Cleaning in Covina.
Air Duct Repair in Covina
Sometimes cleaning reveals the real problem: a disconnected run, a crushed flex section, or a return pulling attic air through a failed seal. In Covina’s 1950s and 1960s-era homes, those findings are common. Once dust is removed, the leaks become obvious. We repair or replace the affected duct sections, reseal the joints with mastic, and then clean the repaired area so you are not paying twice. Every repair gets a written guarantee, and if the repair does not hold inside the coverage period, we come back at no charge. Details on scope and warranty terms are here: Air Duct Repair in Covina.

What pushes a Covina quote toward the top of those ranges is usually age. Homes with original 1960s ductwork, multiple damper zones, or significant post-fire ash buildup take longer to clean properly. Whatever the number, it gets put in writing before we start. No surprise line items after the fact, no per-vent upsell, and no coupon price that mutates when the van arrives.

For single-family homes, no. The work happens entirely inside the existing HVAC system, so no exterior modifications are involved.

- Faith N."We had construction dust packed into every register after a remodel. They sealed off the returns, used negative pressure, and left the floors cleaner than they found them."
- Paul E."I liked that I knew who was coming in. Name and photo texted ahead, badge at the door. He was quiet, careful with the furniture, and thorough."
